PTFE High-Temperature Cable Type Working Voltage

    PTFE High Temperature Cable

    • AC RMS Dielectric Test
    • Voltage for 1 minute Spark Test Voltage for for 1 second
    • ET 250 1500 2500
    • E 600 2000 3400
    • EE 1000 3000 5000


    Thin-wall insulation is not recommended for higher soldering iron temperatures and for gauges larger than AWG 20 Stripping of Tape-Wrapped-Sintered (TWS) PTFE insulation is generally difficult on automatic high-speed machines, more so, for thin-wall finer sizes ADVANTAGES OF PTFE INSULATION


    • Inert to practically all chemicals even at elevated temperatures
    • Excellent Resistance to Ultra-Violet radiation and stress-cracking
    • Non-contaminating, Non-toxic and bio-compatible
    • Resistant to fungus and mould growth


    • Excellent thermal stability — suitable for use from -200°C to 260°C
    • Fire (flame) proof
    • Soldering iron resistant and suitable for high density wiring


    • Suitable for very wide frequency range (DC to above 10,000 MHz) over wide temperature range
    • Lowest dielectric constant (2.1)
    • Lowest dissipation factor (below 0.0003)
    • Highest volume and surface resistivities (in Teraohms)
    • Corona Resistance is fair (CR PTFE is available for severe corona conditions)


    • Smaller size, lighter weight and much higher reliability
    • Cold-flow and cut-through resistance — fair (good mechanical strength)
    • Excellent flex-life
